基于ZigBee技术的输液监控系统的设计与实现

Design and Implementation of Monitoring System for Transfusion Based on Zigbee Technology

为科学有效的监控患者静脉输液过程,研究并设计了基于Zigbee技术的输液监控系统。使用Labview设计上位机监控界面,利用槽型光电开关检测点滴滴速,使用无线传输模块收发数据。设计了一种新型电子夹,通过调整步进电机控制电子夹开度大小,控制滴管横截面积,从而达到控制滴速的目的。经实验证明,系统工作稳定,实现了患者输液过程中的远程监控功能,达到了对点滴滴速的控制要求。

In order to monitor the process of intravenous transfusion of the patient scientifically and effectively, the monitoring system for transfusion based on the technology of Zigbee is researched and designed. Lahview is used to design PC monitor interface. Groove type optoelectronic switch is used to detect dripping speed. Wireless trans- mission module is used to send and receive data. A new kind of electronic clip is designed to control the cross-sec- tional area of the dropper by adjusting the stepping motor, which controls opening size of the electronic clip, so that it can achieve the purpose of controlling dripping speed. Proved by experiments the system works stably, it not only realizes the function of remote monitoring in the process of transfusion, but also meets the requirements of control- ling dripping speed.
